Expecting a baby brings joy and marks the start of a beautiful family journey.
Throughout your pregnancy journey, your medical team will use ultrasound scans to check your health and track your baby’s growth. Therefore, learning about these scans helps you feel calm, prepared and informed for every checkup.
First Trimester: Early Detection Scans
Your medical team schedules scans to confirm your pregnancy and check your health status.
- Dating Scan (6–10 Weeks): Confirms a heartbeat, checks the sac and calculates your baby's exact age.
- Nuchal Translucency (NT) Scan (11–13 Weeks): Measures thickness at the back of your baby's neck.
Consequently, doctors combine NT measurements with blood tests to evaluate genetic probabilities accurately.
Second Trimester: The Anomaly Scan
Between 18 and 22 weeks, you will have an anomaly scan. During this appointment, the technician checks your baby's physical features, including:
- Brain and Spine: Verifies neural tube closure and structural alignment.
- Heart and Organs: Assesses four-chamber heart function and kidney placement.
- Placenta and Fluid: Checks placental position and amniotic fluid volume.
Moreover, this detailed scan also checks that your baby's organs are developing well and looks at where the placenta's placed.
Third Trimester: Growth and Doppler Scans
During the months, your doctor will monitor your baby's growth to plan for a safe delivery:
- Growth Scan: Measures head circumference, abdominal width and thigh bone length to estimate fetal weight.
- Doppler Scan: Evaluates direct blood circulation through the umbilical cord vessels.
Furthermore, these focused checks verify whether the placenta delivers oxygen and nutrients continuously. As a result, doctors gain data to manage high-risk pregnancies effectively.
Advanced 3D and 4D Scans
Among the types of ultrasound scans during pregnancy, modern facilities frequently offer three-dimensional and four-dimensional imaging options:
- 3D Scans: Create static, life-like surface photographs of your baby's facial features.
- 4D Scans: Stream real-time moving video of your baby yawning, kicking or smiling inside the womb.
Therefore, many families choose these procedures to create lasting visual memories.
